SELF-STROPPING- SAFETY-RAZOR.

y following is a full, clear, and exact description.

This invention relates to safety razors and has particular reference to improved facilities for accommodating a plurality of blades at the same time and for adapting the holder for stropping the blades without removing them from the holder.

More definitely stated, the invention relates to an improved form of safety' razor including a head and a handle therefor, one or more razor blade holding devices being permanently connected with the head and adjustable thereon so as to position a blade or blades for either shaving or stropping f purposes.

Among the objects of the invention, therefore, is to improve safety razors so as to make them more readily adaptable for either shaving or stropping purposes, without material interchange of parts, than has heretofore been possible.

The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a side elevation showing the adaptability of the improvement as a stropping device; Fig. 2 is a vertical longitudinal section of the same; Fig. 3 is a plan view; Fig. 4 is a view corresponding to Fig. 2 but with the parts set for shaving one of the blades and its holding yoke being omitted to better disclose the construction; Fig. 5 is a plan view ofthe guard mechanism as seen v from the line 5-5 of Fig. 4; Fig. 6 is a vertical transverse section on the line 66 of Fig. 2; Fig. 7 is a partial side elevation, partial section, on the line 7-7 of Fig. 8; and Fig. 8 is a vertical transverse section on the line 8-8 of Fig. 7.

The several parts of this device may be made of any suitable materials, and the relaspecmcation of Letters Patent. Application mea may 29, i915. seran 1q9. s1,155.

varied to a considerable extent without departing from the spirit of the invention hereinafter more fully described and claimed.

Referring more particularly to the drawlngs, I show a body or head 10 comprising a 'base 11 and parallel side flanges 12. The

base is provided in its center with a socket 13 having an internal thread and counterbored at 14 to receive the upper end of the handle 15. Said end is conical or tapered,

as indicated at 16, adjacent which is a thread 17 coperating with the socket thread, and next adjacent that is ya flange 15 fitted slidably `in the counterbore 14. Except as stated, the base 11 is flat and smooth on its `upper surface where it coperates with a pair of slidable guard members 19 and 20. The side flanges 12 of the head are pro-- vided with -lugs or projections indicated in the nature of inwardly pressed lugs or ribs 21 spaced suiciently above the basel l1 to form keepers or guides for the guard members limiting the movement thereof in a plane close and parallel to thle base 11. Each guard member `comprises a 'series of teeth 22 at its upper edge and adjacent each end of each series of teeth there is formed on the guard plate an upwardly and inwardly projecting lip 23. I y To the inner edge of the guard plate 19 is vsecured a shank 19 `lying in the same plane as the main/portion of the guard 19 and having a hole 19 formed therethrough. The guard plate 20 has an inwardly projecting shank 20 defiected upwardly so .as to lie above the shank 19 and also having a hole 20a. `The tapered end 16 of the handle projects through said holes of the Shanks, but, as shown best in Fig. 5, the .centers of the holes are eccentric to the axis of the handle, and hence, by screwing the handle more or less deeply into the socket, the guard plates will be drawn toward each other proportionally.

I show .and employ a plurality of razor blades 24 each having a single cutting ed e and having its hilt 24 fitted slidably en wise into a yoke 25 formed preferably of sheet metal and carried upon `,a fshaft, v26 eX- tending across thel head above?? edgesof the side flanges 12. A rolleii" 27e'xte'nds through and is journaled in a pair of slots j outside of the flanges 12.

l deinite 28 formed in the opposite portions of the flanges 12 and is held parallel to and at a distance from the shaft 26 by means of a pair of plates 29 lying preferably just A pair of intermeshing gear wheels 30 are secured to the ends of the shaft and roller just described. The main portionsy of the slots 28 are inclined downwardly and outwardly and terminate in upwardly directed seats 28 in whichthe roller 27 is seated and held by the strop 31 during the stropping operation, and at such time the shaft 26 bears outwardly against a pair of shoulders 32 'formed along the upper edges of the flanges 12 whereby the outward swinging movement of the shaft 26 is limited. j

The foregoing description of each razor blade and its actuating and holding devices will be understood as being applicable `to both of them on opposite ends of thehead lll. The strop 31` is presumed to be anchored at one end as usual and'held in the hand at the other, the intermediate portion thereof being threaded through the head beneath the rollers 27 and over a rod or roller 33 extending transversely at thejmiddle portion of the head, but on a line above the plane intersecting the axes of both of the rollers 27 when they are in stropping position. The actionof the roller 33 in thus deiecting the intermediate portion of the stropping 'insures sufficient friction being set up between the strop and the rollers.27v to cause said rollers to turn around their axes and hencecause the rotation of the shafts 26 in the opposite direction through the gears 30.

. Figs. 1, 2 and 3indicate the movement of l alternation.

the head relatively toward the left with the result that.y the blades24 are caused to drag upon the upper surface of the strop. AThe blade that is turned inwardly toward the center of the head rests with its edge upon that portion of the strop passing directly over the roller 33. stroke is made, and the head is moved in the opposite direction, the friction between the strop and rollers 27 causes them to throw the blades in the opposite direction so as to act upon the opposite faces of the edges in After the blades are stropped, the head is simply slipped over one end of the strop, and after the strop is out of the way, the rollers 27 are free to drop to or toward the bottoms of the slots 28 along which they may be moved readily by hand so as to permit the edge of the blade to slip beneath the lips 23- of the guards.v The guards are then tightened by the action of the handle as above described, so as to cause more or less of the cutting edge of each' 'blade to project as much as the individual operator may desire, and in such position the shafts 26 are held from movement with When the end of the i thereby the blades are held in steady osis tion as shown best in Fig. 4. At 2 is shown a lug bent side flanges 12 adjacent the inner edge of the extension or seat 28 of the slot 28, which lug coperates with the other parts to hold the roller 27 steady while -in stropping position. Additional lips 23'1 may be formed at the corners of the guard plates which, extending upwardly and inwardly, constitute positive stops limiting the outward move ment of the blades.

I claim 1. In a safety razor, the combination of a head comprising a pair of parallel side flanges. having alined .bearing 'openings formed therein, a handle having removable threadedconnection with the' head and having its end projecting .between said flanges, a razor blade, a holder for the blade, means controlling the position of the vholder and blade including a roller jour-4 naled in said alined openings, and a guard plate movable along the head between said said guard coperating with the face thereof, a razor blade, holding means for the blade including a roller journaledv in said slots and movable along the same inwardly or outwardly with respect to the axis of the handle, and a guard plate fitted movably against the outer surfacevof the base and having a shank coperating with the projecting end of the handle, said guard including means interlocking with the ends of the razor blade to hold it steady in position.

3. In a safety razor, the combination of a body including` a base and parallel side flanges, said base having a central socket, a

.handle secured in the socket and having a tapered end projecting upwardly beyond the upper surface of the base, a pair of guard plates fitted slidably against the outer surface of the base along opposite ends of the head, each guard plate having a shank with a hole therethrough into which the tapered end'of the handle extends, the centers of the holes being eccentric to the axis of the handle, a pair of razor blades having their edges coperating with the means to secure the blades 1n place.

4. In a safety razor, the combination of a rigid head having parallel side iianges, a pair of guard plates fitted in the head and adjustable longitudinally thereof between the flanges, means extending inwardly from guard plates, and.

inwardly from each of the the flanges, confining the guard plates for between the guard plates and the ends of movement longitudinally of the head only, the bladesfto lock them in shaving position. means to adjust the guards as aforesaid and hold them in adjusted position, a pair of ETHEL CLEVELAND *GALLUP razor blades, means cooperating With the Witnesses: side anges to position the blades with re- GEO.
